When choosing new doors and windows for your home or project, security is often top of the list — and rightly so. One term you’ll likely come across in product specifications is PAS 24, but what does it mean, and why is it important?

In this guide, we’ll explain what PAS 24 is, why it matters, and how it fits into modern building standards in the UK.

What is PAS 24?

PAS 24 stands for Publicly Available Specification 24. It’s a UK security standard that defines the minimum performance requirements for enhanced security in doors and windows. Products that meet PAS 24 have been tested to demonstrate their ability to resist various common burglary methods.

Unlike some other standards, PAS 24 is a pass/fail certification — meaning a product either meets the security criteria or it doesn’t. There’s no grading scale, which gives homeowners and professionals confidence in what the certification actually guarantees.

Why PAS 24 Matters

For property owners and developers, PAS 24 certification is a mark of trust. It confirms that a door or window has been independently tested against methods typically used by intruders, such as forced entry, mechanical attacks, and physical impacts.

Whether you’re upgrading a residential property or specifying products for a new-build project, using PAS 24-compliant doors helps ensure long-term protection and peace of mind.

What’s Involved in PAS 24 Testing?

Products undergo a rigorous series of tests to qualify for PAS 24. These tests are conducted by accredited third-party organisations and include:

• Manual attack simulation – Using tools and force to test points of vulnerability.
• Mechanical loading – Applying pressure to locking points and hinges to assess strength.
• Impact testing – Replicating real-world attempts to breach the product through kicking or striking.

Only products that pass all tests are awarded PAS 24 certification.

PAS 24 and UK Building Regulations

For new residential developments, especially in England and Wales, compliance with PAS 24 is often a legal requirement. Under Approved Document Q of the Building Regulations, secure windows and doors must be installed in all new dwellings. PAS 24 provides a clear and reliable way to meet this requirement.

Using PAS 24-certified products helps developers, architects, and installers ensure full compliance with current regulations.
